This is the package in which a component's code is executed. For historical reasons, this defaults to HTML::Mason::Commands.

preamble

Text given for this parameter is placed at the beginning of each component, but after the execution of any <%once> block. See also postamble. The request will be available as $m in preamble code.

postamble

Text given for this parameter is placed at the end of each component. See also preamble. The request will be available as $m in postamble code.

use_strict

True or false, default is true. Indicates whether or not a given component should use strict.

use_warnings

True or false, default is false. Indicates whether or not a given component should use warnings.

named_component_subs

When compiling a component, use uniquely named subroutines for the a component's body, subcomponents, and methods. Doing this allows you to effectively profile Mason components. Without this, all components simply show up as __ANON__ or something similar in the profiler.

define_args_hash

One of "always", "auto", or "never". This determines whether or not an %ARGS hash is created in components. If it is set to "always", one is always defined. If set to "never", it is never defined.

The default, "auto", will cause the hash to be defined only if some part of the component contains the string "ARGS". This is somewhat crude, and may result in some false positives, but this is preferable to false negatives.

Not defining the args hash means that we can avoid copying component arguments, which can save memory and slightly improve execution speed.

ACCESSOR METHODS

All of the above properties have read-only accessor methods of the same name. You cannot change any property of a compiler after it has been created (but you can create multiple compilers with different properties).

METHODS

This class is primarily meant to be used by the Interpreter object, and as such has a very limited public API.
